[s-cars] miss at idle

[Matthew Russell]

Hi Gang-

92 s4, 186,000 miles, original coils and POS's if you can believe it!

I've followed the diag instructions on audiworld and Charlie's site  
(thanks Charlie and Dave F)) but haven't come to any definite  
conclusions.
Symptom is miss at idle and under load (I think, hard to tell in 35mph  
zone!), unplugging connector for injector 2 causes no change so i'm  
guessing that's the problem cylinder.  Swapped to the extra "channel"  
of the POS , no change.  Swapped in known good plug and boot, same.   
so i'm suspecting coil at this point.  Other ideas or am i on the  
right track?

2 more questions: aftermarket source for a couple coils or dealer  
only? I'm not planning on going to the 1.8 conversion at this point.   
Anyone have some in the Rossato bin (tm) for sale?

and finally, those 3 and 4 pin connectors were SUPER brittle and  
partially crumbled away when switching the connections so I'd like to  
replace them.  Dealer only? anyone have a harness from a 1.8t coil  
pack conversion lying around or are those connectors reused at the 4  
pin (ecu signal) side?

TIA for any help,
